Welcome to LogicWorks and the world of interactive circuit design. As electronic systems have become more complex, operating speeds higher, and custom chip technology more widespread, software tools for engineers have become an essential part of the design process. It is no longer possible for an individual engineer or a corporation to remain competitive while using pencil and paper for design. Powerful computer-aided design (CAD) programs have been commercially developed to meet the increasing demands facing industry. At Capilano Computing Systems Ltd., our flagship product, DesignWorks , is used in government, industrial, and academic labs worldwide, providing users with speed, ease of use, and affordability. Many instructors want to give their students hands-on experience with CAD tools used in industry, but the high cost and complexity of most commercial CAD programs limit their use at academic institutions. In light of this situation, we developed LogicWorks, the student version of DesignWorks, to be used by students in lab settings and by instructors as an interactive teaching aid. LogicWorks was created with the following goals in mind: to give the student an introduction to the concepts and practicalities of using CAD tools; to provide a "virtual workbench" that allows the student to quickly test out circuit design ideas and document results; to be intuitive and easy to use, so that time is not wasted on the details of installing and operating the software; to provide the features and interfaces necessary to work with current design technologies; to provide an upward path to professional design tools used in industry.The major change in LogicWorks 5 from previous versions is the addition of VHDL simulation. VHDL has become the industry standard method for describing digital systems in a high-level language, and an understanding of it is now essential for any working circuit designer. VHDL is a huge language, and LogicWorks does not attempt to provide a full implementation in this version. Our goal is to present the features that are most commonly used and taught, and to keep the package easy to use and low in cost.
